New Dan Brown book

I am currently reading the new Dan Brown book, The Lost Symbol and i am only about half way through right now, but i cant help but think about if some of the things in that book are really true. I know that i large number of the details are fiction, although Brown states that many are actually factual. That i do not know. I am not a historian and therefor do not have proof.
One thing that i cant get out of my mind is the research that is preformed in the lab during the book by Kathrine Soloman. Is it really possible to change things by just putting all of your hope onto things? This i want to find out. People always told me not to give up hope and this makes me want to hope and wish harder.
Since i am only half way through the book i dont know whether the research is real or what happnes to it. But even though it is unlike Brown's other books, he always has me thinking. I question religion in general and most of that is unanswered questions my whole life and many things that Brown brought up has made me consider what beliefs we are supposed to have. Isnt it funny how a couple books can change your outlook on life. I almost wish there were more books out there that did make me think and question things.
